REMOVING GROUP SCAN CHANNELS
To DELETE a programmed channel from the GROUP SCAN MEMORY.
1. Rotate the CHANNEL SELECTOR switch until the channel you wish to remove is dis­
played. Note that the ME should be Indicated on the CHANNEL indicator, indicating
that this channel is currently programmed in the memory.
2. Press and hold the MEM switch for about 2 seconds until a BEEP is heard twice. The
ME should now be extinguished.
OPEN SCANNING
To commence open scanning, select the OPEN SCAN mode by pressing the GROUP
switch. The G is disappeared. Then press the SCAN switch.
The UH-055 will commence scanning the programmed channels, and will indicate each
channel on the CHANNEL indicator as it Is scanned.
When a busy channel is found, the radio will 'lock' onto it. and will remain there for as long
as the signal is present, and for 3 seconds after the transmission ceases. This allows the
UH-055 to hold the channel during short breaks in the conversation. Once the channel has
remained clear for 3 seconds, the radio will resume scanning.
If you don't wish to listen to a busy channel, you can SKIP over it by pressing the MEM
switch. The receiver will immediately resume scanning.
When you stop scanning, press the SCAN switch again.
NOTE: 1. During OPEN SCAN mode, the CHANNEL SELECTOR switch and PTT
switch is ignored.
2. The scan rate in SCAN FAST mode is 70 msec per channel, i.e. all 40 chan­
nels can be scanned in 2.8 seconds.
GROUP SCANNING
NOTE:
1.
If the GROUP SCAN MEMORY has not been programmed when the GROUP SCAN
Mode is selected by pressing the GROUP switch and the SCAN switch is pressed, the
UH-055 will ignore the SCAN switch and a BEEP is heard. It will behave as if it had not
been pressed.
2, The PRIORITY channel number can easily be read when required by:
(a) Stop scanning by pressing the SCAN switch.
(b) Pressing the PTT switch. The radio will jump to the PRIORITY channel for 3 sec­
onds before resuming the SCAN function.
To commence GROUP SCANNING, select the GROUP SCAN Mode by pressing the
GROUP switch and select the SCAN mode by pressing the SCAN switch.
The UH-055 will now scan the programmed channels, displaying each channel num­
ber and the PRIORITY channel number. Because, before it scans each channel, it
quickly "checks” the PRIORITY channel (set by the CHANNEL SELECTOR switch).
